PITTSBURGH (Newsradio 1020 KDKA) - The United States of America changed forever 17 years ago after the September 11th terrorist attacks.

The passengers and crew members of Flight 93 intervened that day, managing to save a countless number of lives by overtaking that plane.

Stephanie Loeb, Public Affairs Specialist with the National Parks Service, joined KDKA Radio on Tuesday to talk about how the National Park Service will be honoring the victims of Flight 93, 17 years later.

What will be taking place at this morning's ceremony?

At 10:03, the approximate time that Flight 93 crashed here in Shanksville, we will have 40 representatives reading the 40 names of the passengers and crew members while ringing the bells of remembrance,” said Loeb.

What can visitors expect at the Flight 93 National Memorial?

“You will now be greeted by our Tower of Voices, a 93 foot tall, concrete structure that is filled with wind chimes. That is something that really sets the tone when you walk into the park, it reminds you that this is a very solemn and sacred place,” Loeb tells Larry and John.

“Once you come down to the visitors center you will see a black walkway. That in fact is the flight path. You can take that all the out to what we call the flight path overlook, which looks down at the memorial plaza, the wall of names, and the crash site as well.”

Is the site of the crash family only?

"Yes. Traditionally we open it once a year on September 11th for families to go out there and pay their respects to their loved ones," Loeb tells listeners.

One of those who will be there Tuesday is Kenny Nacke. He lost his brother on Flight 93. He talked to Larry and John about the anniversary and what he went through on September 11, 2001.

Does time help the healing process?

“Yeah, for me, coming out here to the memorial, seeing it grow, seeing how it has changed. The land has healed,” Nacke said.

“It kind of gets you to the point where you kind of celebrate their lives, as well as missing them.”

What’s your reaction to the “Tower of Voices” and the sound it makes?

“It’s iconic,” Nacke tells KDKA Radio.

“When you look at it, it actually looks better than all of design pictures that we saw when we were in the process of designing and building the memorial.”

Did your brother make a phone call before the crash?

“No sir, and I don’t think he would,” said Nacke. “Those 40 individuals, in 30 minutes, were able to do something incredible, astonishing. They were able to make phone calls, gain information, come up with a plan, and then they executed it. I think that’s amazing in itself. They gave their lives so we can continue to live our lives.”
